' late the pressure and to compensate for shrinkage olthe rolls.

The accon'ipanying drawings illustrate one practical embodiment of theinvention,

and I will explain the invention with referi 1 once thereto to enableothers to adoptand use the same. In the claims the novel features ofconstruction and comblnations' of parts for which protection is desiredare sinnmarized.

In said draw1ngs:- W .iligure l is a top plan view of a: port1on ot theinking mechanism of a printing press showing my improved ink-rollersupports. Fig. 2 is an enlarged side view of one of the roller supports.

Fig. 3 is an end view of Fig. 2.

ln the drawings. I have shown the invention as used in connection withan ordinary inking mechanism having an ink distributa suitableconstruction. Cooperating with this drum is adistributing roller R-which is journaled in adjustable supports, each COI11 prising asupporting member 1 and a complemental member 1 hinged to the member 1at 1. Member 1" can be securely locked against the member 1 so as toenclose and support the roller journal. As shown ascrewflis pivoted at 2toalugon the upper side of member 1, and is adapted to be en gagged witha bifurcated lug 1 on the up per side of member 1". /Vhen the member 1*is closed against the member 1, as in 2, the bolt 2 is dropped intoengagement with the lug- 1. and clamped thereagainst by a wing-nut 2 asindicated in the drawings.

Member 1 be raised or lowered, and has a dog or tooth P on its lowerside by which the opening or lowering movement of the member 1 islimited.

The roller supports are adjustably mounted on the frame F by means ofrearwardly extending arms 1 on members 1 engaging slots 7 in the frame.Each arm 1 has an elongated slot 1 (indicated in dotted lines in Fig. 2)through which passes a bolt 3 which is tapped into the frame F. Themember 1 also has a slotted lug 1 on its upmay be, of welhknownconstruction.

per side which is rotatably engaged with a screw at tapped intotheframeF above the arm 1*; said screw havmg a header and a collar 4 betweenwhich the lug 1 closely fits.

The partsas thus far described are, or

It is necessary to have the rollerR adjustable. so as to cause it tobear on the 1nk drum orjtorm (as the case may be) with more or lesspressure, and to take up shrinkage of j the ink roll. This adjustment iscommonly made by ad usting arm 1 in the slot in the frame by means 01"screw 4 and when adjusted to the satisfaction ot the operator the rollsupport is clamped firmly in place by tightening bolt3; So tar this iscommon construction and practice. It 1s obvious and a stiff spring" 5which may be any suitable kind. (beingv shown as a metal spring) isinterposed between the shank 1 nd the head 3 of the bolt 3. This springmust be stiff enough to firmly hold the socket arm against the frame byfrictional contact and to resist displacement bythe normal pressure onthe ink roll, and yet be yielding; enough to allow the screw 4 to beoperated for adjustment.

Washers 3 -3 are preferably used on bolt 3 to square or center thespring 5 so it will press evenly on the arm 1 and the head of the bolt3.

With this simple improvement the setting of each rollsupport requiresonly one operation instead oi: three as outlined above.

There are ordinarily twenty-eight ink roller sockets to be adjusted onevery sixteen page printing section. In an octuple press consisting; offour sections obviously there are l12such roller sockets. Each suchrollor socket heretofore has required three operations to adjust it butby my invention only one is required, the amount of work and that suchadjustment requires three opera- MODS-01 each support: first arm 1 mustbe equipped 'With my improvement, could have all the rollcrsadjusted intwenty-eight opertions. The placingof-this improvement on the rollersocket means that 112 operations instead of 336 operations, arenecessary in making the adjustment for the full complement of rollersonan octuple press.

thumb nut 2* is unscrewed and the I-bolt 2 with. thumb nut lifted clearof the slot in lug l-then the cap member 1 can be swung downward on itshingeuntil the lug l strikes the lower edge of further revolving aroundits hinge, and the roller R can then be readily? removed or reandcoacting distributing rollers; inking roller supports adjustably mountedon the frame; friction means for the supports in any adjusted position;and means for adjustingsaid supports relative to the frame Withoutchanging the adjustment of said friction means. j
